The full Moon will become colored a mesh of reddish-orange, with hints of turquoise, as it passes into the shadow of Earth after rising over the eastern horizon and after the Sun has sunk beneath the western horizon on Wednesday evening.

The entire total lunar eclipse is visible from South America and most of North America. To see the fantastic display in the evening sky, go outside and watch this beautiful event. If you miss it this year, you won’t be able to see a total lunar eclipse again until December 2010. A penumbral eclipse begins at 8:36 EST (00:36 UT), followed by a partial lunar eclipse at about 8:43 p.m. EST, and then followed by the beginning of the total eclipse at about 10:01 p.m. EST. The total eclipse will last until about 10:51 p.m. EST (05:51 UT), with the end of the partial eclipse at about 12:09 a.m. EST and the end of the penumbral eclipse at 12:16 a.m. EST. A lunar eclipse is the result of the Earth being directly between the Moon and the Sun. The Earth, thus, blocks the rays of the Sun from impinging on the surface of the Moon.
The atmosphere of the Earth—the stratosphere—redirects (refracts) the light coming from the Sun (scatters it) so that it becomes reddish-orange in color, which is why we often see a reddish sunset at dusk. The amount of scattered light depends on the amount of dust in the atmosphere. The more dust, the more scattering of light, and the deeper coppery-red color seen on the Moon. |
